When is it appropriate to watch A Brief History of Time?

Don't worry if you don't understand it, because after all, it is a relatively marginal problem, and you also need to have a certain amount of philosophical and scientific thinking. After finishing high school, you should be able to understand a little.

In the future, you can review it every once in a while, and if you still have to study in science, you will continue to gain something.

I started watching it when I was 3 years old. I don't understand either.

You can watch it whenever you want to, different periods will have different understandings, and every time you watch it, you will have a new harvest.

I watched it when I was a freshman in high school. In fact, you can watch it at any time, it's not for the exam, the college entrance examination is not taken at all. It's just that as a hobby, you can watch it as long as you want. The content is very deep, but the expression is actually very shallow.

I advise you not to look at it, it's boring and useless.

Unless you're planning to study physics at university, there's no need to study physics as a major.

It's all empty stuff, or should you look at something that meets the needs of high school students.

I think you can read a brief history of time in the first year of junior high school, take a closer look!

First, more than 300,000 children around the world are watching it!

Second, treat him as an extracurricular book, and read as much as you want.

Thirdly, there is something in it that is acceptable.

Fourth, I read a brief history of time in the first year of junior high school, and the first chapter is acceptable.

It is more suitable for the younger generation and curious people. One is an illustrated book, and one is a popular version. The popular version, the translation is a bit jerky, and some places are difficult to understand, and it fails to show Hawking's humorous and easy-to-understand expression.

It is recommended to choose an illustrated book, which is easy to understand.

One. Brief introduction. A Brief History of Time: From Big ** to Black Holes is a popular science model written by British physicist Stephen William Hawking in 1988 to popularize advanced theoretical physics. It talks about the origin and fate of the universe, mainly introduces what the universe is, the latest state of the development of the universe and the most cutting-edge knowledge about the nature of the universe, and explains astrophysical theories such as black holes and big **.

Two. Introduction.

Cosmology is a discipline that is both old and young. As higher beings in the universe, human beings are not satisfied with their own existence and the continuation of their race, but have also relentlessly explored the meaning of existence and life from generation to generation. However, the evolution of the human mind is extremely slow and painstaking.

It took 2,000 years to evolve from Aristotle's Ptolemy's geocentrism to Copernicus Galileo's heliocentrism. Surprisingly, despite the fact that everything in the world is in motion, it was only in the 20s of this century that the idea of the evolution of the universe entered human consciousness after Hubble's discovery of the law of redshift. It never even occurred to people that the universe would evolve.

Newton's law of gravitation states that the matter of the universe cannot be in a stable state under gravity. Even in Einstein's theory of general relativity, the situation was not much better, and in order to get a stable model of the universe, he introduced the cosmological constant into the theory. They all hope to find a stable model of the universe in their theories.

It must be an illustrated book, I read it when I was a freshman in high school, and the only thing you have learned so far is the atomic content at the beginning of chemistry, and the limited content of optics (wave-particle duality) in physics in the second and third years of high school.

A brief history of time mentions the characteristics of many particles, because to unify the four forces (strong nuclear force, weak nuclear force, gravitational force, electromagnetic force), the more you explain the small particles, the easier it is to unify, remember that it seems that the grand unification theory has unified the three forces except gravity, and Hawking also assumed that virtual particles unify gravity, but virtual particles are not yet mature. There are many theories in the book that require the foundation of quantum mechanics, such as the uncertainty theory, Pauli's incompatibility principle, and many other theories. These are things that even science undergraduates can't learn (except for physics, I'm not a physics major), and quantum mechanics seems to be a book that only graduate students read.

I remember when I watched it every day chasing the physical chemistry teacher, they were going to get hairy when they asked, a lot of things I didn't understand, very helpless, because I didn't learn optics in the first year of high school, I even had to ask the teacher about white heat and red shift, it was really sad but proud of 2 months, and finally I finally understood it.

Highly recommended illustrated version, illustrations and the more the better, you must not be shy when you look at it, do not dare to ask, chase after the teacher to ask clearly, understand this can greatly develop your interest in astrophysics, maybe you will apply for an undergraduate degree in physics in your third year of high school.

I hope what I said helped you.
